1431-79-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1431-79-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,3 and 1 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1431-79:
(6*1)+(5*4)+(4*3)+(3*1)+(2*7)+(1*9)=64
64 % 10 = 4
So 1431-79-4 is a valid CAS Registry Number.
